RADIATOR-HEATER.

Specification of Letters Patent. y Patte-Hwa July 3, 1917,

Application filed January 5, 1915. Serial No. 591.

To all whom t may concern.'

Be it known that I, EUGENE B. WALsH, a. citizen of the United States, and a resident ci the borough of Brooklyn, city of New Vork, county of Kings, and State of New York, have invented certain new and useful Improvements in Radiator-Heaters, of which the following is a specification.

The present invention relates to radiator heaters. One object of the invention is to provide a separately constructed heating attachment for heating radiators, which may be attached to or used in conjunction with a radiator which is otherwise'complete. The present device is adapted'to be attached to the ordinary forms of radiators now in general use without any special construction or reconstruction of the radiator. Thus it is possible to use a common form of radiator in conjunction with vthe heater to provide a complete heating unit. Or, it is Ipossible to attach the present device to one. or more radiators which already form part of a heating system .having a number of heating units, whereby the separate unit may be independently used for heating when the system as a whole is not 'in operation or where the system as a whole is not providing as much heat as is desired from the particular unit referred to.

A further object of the vinvention is to provide a radiator heater having a novel form of base or receiving compartment, for the radiator, which will so inclose part of the latter as to produce a maximum quantity of heat with a minimum consumption of fuel by permitting the proper portions of the radiator sections to be inclosed orsubl jected to the action of the iame to obtain the best results. Y

Another object of my invention is to provide a heater which may be so combined with an ordinary radiator as willprovide a compact and not unsightly combination.4

Another object thereoil is to provide a heater having the above characteristics and which may be very easily attached to or detached from a radiator With the least skill and labor.

Another object of my invention is to pro vide a heater which may be very easily made in any size or length to accommodate a radiator of desired size or having any desired number` of sections.

In the drawings forming part of this ap- 'pl1cation,

Flgure l, is a plan view of a heater embodying my invention, attached to an ordiv regular steam vary; but I have illustrated my invention attached to a radiator of common form, having six sections.

I have shown a radiator l, which comprises a series of sections 2 and it may be connected with an ordinary steam or hot water system by means of 'the usual pipe 13a or this end of the radiator may be blocked and the radiator used'as an independent unit. The radiator has the usual legs 4 at the several corners thereof and the several sections are connected to be 1n communlcation with each other by the usual connections 5.

The device comprising the invention consists of. a base or compartment 7, which is preferably of-a portable and detachable na-v ture and of rectangular shape. This compartment is preferably formed of end members 8, 9 each having two legs 10, and preferably made as arcasting, and the plates 1,1, 12, extending between the end plates and at their ends secured thereto, as by means of the screws 13. The plate 12 constitutes the rear wall of the combustion compartment 14, and from the top thereof extend the projecting plates 15. These latter extend forward and between the several sections 2 of the radiator and coperate with similar plates projecting from the front'wall, to'

form the top closure for the combustion chamber. The number and disposition of -sections will vary in number rather than otherwise, according to thenumber of sections of which the di'erent radiators are composed. Since the front and rear walls are separate from the end walls 8, 9 they may be made of sheet metal of considerable length and then cut into various lengths to suit radiators having different numbers of sections. This facilitates the application of the invention to radiators at present in use.

The front wall 11, is similar to the rear' wall and it is attached to the end walls in a similar manner. It has plates 17 extending rearward over the bosses 5 at the lower ends of the radiator sections, similar to and preferably slightly overlapping the plates 15.

The plates 15 and 17 constitute the top of the combustion chamber and they prevent the escapev of the heat therefrom immediately; but, since there must be some escape for the heat which is continually generated the plates 15, 17 are preferably so made as to only partially close the spaces 16, between the radiator sections., thus leaving spaces 18 which will permit the heat to escape upwardly and along the Aradiator sections, whereby the -heat will be utilized to the fullest extent.

The radiator is partiall received in the combustion chamber, that 1s, the lower ends of the sections 2 and the connections 5 are inserted in the combustion chamber and the legs 4 of the radiator -are received on the tops of the legs 10 of the heater, inside .the end and sidewalls.- Thus the radiator is supported by the heater a slightly vgreater distance above the floor than ordinarily.

There is a pipe 19 extending through an aperture 20 in each end wall and it is capped at one end, 21. v

This pipe has apertures 22 along the top and it serves as a burner for whatever fuel is to be used for heating such, for instance, as gas. This pipe 19, is arranged below the connections 5 and under the sections 2 and between the legs of the radiator, and in this position it is adapted to heatA the water or steam in the sections and in the connections 5.

The bottom ofthe combustion chamber is preferably double and so arranged as to admit an ample supply of air for combustion and also prevent the heat from radiating downwardly from'the burner to the floor.

v For this purpose I have provided a bottom plate 23, which rests upon the legs 10 and is supported thereby. This plate has slots or openings 24 extending a substantial part of its length and at each side of the burner 19, to permit air to enter the combustion chamber to facilitate combustion. The plate 23, is bentvupwardly to form baffles 23a at the inner edges of the openings 24. These baffles prevent theJ air which enters 4the openings 24 from blowing out the flame of the burner when it is turned'low.`

' The bottom is also composed of a plate 25 which has its opposite sides, turned up at 26 and then inwardly at 27 so as to -rest upon the side edges of the plate 23 and thus support the plate 25' on the plate 23 and in spaced relation thereto. The space 28 between the plates 23 and 25 is open at'both ends of the latter.l The air enters at these open ends, travels more or less along the space 26 and passes upwardly through the openings 24 into the combustion chamber.

There is thus a continuous supply of air from below. Owing to the double bottom and th'e passage of the cooler air through the space 28 the heat in the combustion chamber can not injuriously affect the floor.

There is preferably provided a door 29 in the front wall, having a handle 30, to provide access when lighting the burner.

The above parts constitute the heating portions ofthe device.

The numeral 31 indicates any form of thermostatic or pressure valve which is connected to the pipe section 6, to communicate with the interior of the radiator sections, and it is adaptedto coperate with a valve 32 interposed in the'supply pipe 33.4 The pipe 34 connects with the supply pipe 33 and leads to a mixing chamber 35 communicating with the burner 19. The supply of fuel through the pipe 33 and into the mixing chamber 35 is regulated by a valve 4() which is preferably of the needle type. The casing of the diaphragm or other valve communicates with the pipe section 6, so that the radiator if not connected to a water supply system may be supplied through an opening by unscrewing and removing the plug 37. A glass gage 38 also communicates with the upper and lower portions of the diaphragm casing for the purpose of indicating the height of the water lin the radiator.

Any kind of fluid may be used for fuel, common illuminating gas being well adapted for the purpose.

In Figs. 1 to 4 I have shown the device combined with a radiator which is independent of' any general heating system, but it may, if desired, be applied to a radiator which forms one of the units of a heating system. In that case it will be possible to' heat the single unit or radiator when the system as a whole is not, for any reason, capable of meeting the requirements. In such use of the device the heater will be constructed and applied as herein described, except that the end wall 8 will be'constructed like 'the end wall 9, asshown in Fig. 5. rlhat is,

it will have anopening 39 through which a pipe 13, which is connected with the heating system, may be passed and be connected withone of the connections 5.

The operation of the device will be lvunderstood from the foregoing description. `When nthe valve 4:0 is opened to admit gas frdm the supply/.pipe 33 it will enter the extension 41 Where it is controlled by the thermostat and it will then pass through the pipe 34, the mixing chamber 35 and burner 19, and combustion will take place above each of the holes 22. The heat generated in the chamber 14 will efl'ectually heat the Water in the lower portion of the radiator and a'portion thereof will be generatedinto steam which will circulate through the radiator sections and the heat will radiate from the latter into the room.' There is no escap'e for the water or steam so that there will be no rapid loss of water, and the radiator will need to be supplied with water only ,at long intervals.

It will be noted that the ordinary form of radiator may be used without modification. Since the radiator legs 4 rest upon the legs 10 which carry the weight of the radiator the construction of the heater as a whole may be light and inexpensive. There need be no permanent connection bel tween theradiator and heater, so that the latter may be removed, leaving the former intact.
